SOUND SEAL
PRODUCT QUIETS ROOMFUL OF BUZZ SAWS!
If you've ever
used a power saw in the basement, your family was probably
more irritated with the noise than excited about your creation.
Imagine what a saw mill sounds like!
Les Wagner,
Owner of Wagner Millwork, Inc., , in Owego, New York, didn't
have to imagine anything; his compact, efficient sawmill
cuts and planes hardwood from raw logs for the furniture
industry.
After renovating
the building, he found that the new walls and ceilings contributed
to a significant increase in noise levels. It was a problem
that Les and his insurance company wanted resolved for the
comfort and safety of his employees.
He turned to
his local Sound Seal representative Bob Andres, of Oshex
Associates in Syracuse for help.
Together they
assessed the problem. The noisiest part of the operation,
the actual sawing, could not be isolated because every piece
of equipment had to remain accessible to perform that function.
Acoustic enclosures were considered impractical. Instead
of isolating the noise at the source, they decided to treat
the environment. More than 600 ceiling baffles reduced overall
noise levels by 8 db(A). The cost of a standard 2'x4' polywrap
baffle is substantially less than any other noise reduction
treatment.
Bob recommended
that a large quantity of Sound Seal Polywrap Acoustic Baffles
be suspended from the ceiling throughout the entire mill.
Since the ceiling height was less than ten feet, the suspended
baffles placed a great deal of absorption close to the noise
sources.
The customer's
goal of a 5 dB(A) noise reduction was exceeded. By virtually
eliminating reverberation as a factor, noise levels were
reduced by approximately 8 dB(A) throughout the entire mill.
Even better, the cost of the project was so low that Les
was well satisfied.
In fact, Les
was so pleased with the results that he arranged for Bob
to speak to his colleagues at the Lake Ontario and Lake
Erie Swayers and Filers convention. The contacts made during
that meeting have led to more work for Oshex Associates
and United Process.
Les and his
employees now work in a much more comfortable atmosphere.
Besides the obvious benefits of increased productivity and
a quieter place to work, Les knows that his operation will
always be in compliance with OSHA noise standards - and
there's a lot of comfort in that!
Sound Seal Polywrap
Baffles are an effective tool to improve room acoustics.
The cost, even in large quantities, is affordable to virtually
